es6的async await讓異步變成了同步的寫法,在vue中,能夠經過封裝axios,使得全部的請求均可以使用同步的寫法。vue
新建一個api.js文件,全局建立api實例ios
import axios from 'axios' const qs = require('qs') const api = { async get (url, data) { try { let res = await axios.get(url, {params: data}) res = res.data return new Promise((resolve) => { if (res.code === 0) { resolve(res) } else { resolve(res) } }) } catch (err) { alert('服務器出錯') console.log(err) } }, async post (url, data) { try { let res = await axios.post(url, qs.stringify(data)) res = res.data return new Promise((resolve, reject) => { if (res.code === 0) { resolve(res) } else { reject(res) } }) } catch (err) { // return (e.message) alert('服務器出錯') console.log(err) } }, } export { api }
使用能夠參考以下es6
import { api } from 'common/js/api' export default { data () { return { list: [], } }, created () { this.getList() }, methods: { async getList () { let {data} = await api.get('/test/list') console.log(data) this.list = data } }, }
